Description

Die Erfindung betrifft eine Einrichtung zum Befestigen einer in einem Dämpfergehäuse zumindest teilweise verschiebbar aufnehmbaren Stange eines Feder-Dämpfer-Systems an einem Karosserieteil eines Kraftfahrzeugs.The invention relates to a device for securing a rod in a damper housing at least partially slidably receivable rod of a spring-damper system to a body part of a motor vehicle.

Eine derartige Befestigungseinrichtung ist aus der FR 2793732 bekannt. Die Befestigungseinrichtung umfaßt einen Träger, über den die Stange mit dem Karosserieteil elastisch verbunden ist. An dem Träger ist ein erstes Federelement vorgesehen, das zum elastischen Aufnehmen und Dämpfen einer Schwingungsbelastung in einer zur Axialrichtung der Stange senkrechten Richtung, also Radialrichtung, von der Stange in das Karosserieteil und umgekehrt ausgelegt ist. Ein zweites Federelement ist gemäß der Befestigungseinrichtung der FR 2793732 vorgesehen, um die Endspiralwindung zum Abstützen einer Spiralfeder des Feder-Dämpfer-Systems an dem Träger elastisch tragend aufzunehmen. Ein drittes elastisches Federelement ist an der Stange befestigt, um als elastischer Anschlag Überschwingungs-Belastungen im wesentlichen in Axialrichtung der Stange von dem Dämpfergehäuse in den Träger einzuleiten und zu unterdrücken. Zwischen dem zweiten elastischen Federelement und dem Träger ist ein Wälzlager angeordnet, dessen eine Lageschale durch den Träger selbst gebildet ist.Such a fastening device is known from FR 2793732 known. The fastening device comprises a support, via which the rod is elastically connected to the body part. On the carrier, a first spring element is provided, which is designed for elastic absorption and damping of a vibration load in a direction perpendicular to the axial direction of the rod direction, ie radial direction of the rod in the body part and vice versa. A second spring element is according to the fastening device of FR 2793732 provided to resiliently receive the Endspiralwindung for supporting a coil spring of the spring-damper system to the support. A third elastic spring element is attached to the rod to initiate and suppress, as an elastic stop, overshoot loads substantially in the axial direction of the rod from the damper housing into the carrier. Between the second elastic spring element and the carrier, a rolling bearing is arranged, whose bearing shell is formed by the carrier itself.

Es ist nachteilig bei dieser bekannten Befestigungseinrichtung, daß sie nur mit einem hohen Montageaufwand betriebsfertig an dem Karosserieteil eingebaut werden kann. Denn das Wälzlager sowie das zugeordnete dritte Federelement kann nur montiert werden, sobald der Träger sowie das erste und zweite Federelement an der Stange des Feder-Dämpfer-Systems und dem Karosserieteil angebaut sind. Vor allem das genaue Positionieren des Wälzlagers sowie des dritten Federelements ist schwierig realisierbar in Anbetracht der hohen Federkraft der Spiralfeder, die unmittelbar auf das Wälzlager einwirkt. Mit dem hohen Montageaufwand gehen hohe Fertigungskosten einher, weswegen die bekannte Befestigungeinrichtung insbesondere für hohe Stückzahlen unwirtschaftlich ist.It is disadvantageous in this known fastening device that it can be installed ready for operation on the body part only with a high installation cost. Because the rolling bearing and the associated third spring element can only be mounted as soon as the carrier and the first and second spring element are mounted on the rod of the spring-damper system and the body part. Above all, the exact positioning of the rolling bearing and the third spring element is difficult to achieve in view of the high spring force of the coil spring, which acts directly on the rolling bearing. The high assembly costs are associated with high production costs, which is why the known fastening device is uneconomical, especially for high volumes.

Es ist Aufgabe der Erfindung, die Nachteile des Standes der Technik zu überwinden, insbesondere eine Einrichtung zum Befestigen einer in einem Dämpfergehäuse zumindest teilweise verschiebbar aufnehmbaren Stange eines Feder-Dämpfer-Systems an einem Karosserieteil eines Kraftfahrzeugs bereitzustellen, das leicht herstellbar und auf einfache Weise in das Kraftfahrzeug einbaubar ist.It is an object of the invention to overcome the disadvantages of the prior art, in particular a device for fixing a in a damper housing at least To provide partially displaceable recordable rod of a spring-damper system on a body part of a motor vehicle, which is easy to manufacture and easy to install in the motor vehicle.

Diese Aufgabe wird durch die Merkmale von Anspruch 1 gelöst. Danach ist jedes Federelement mit einem Trägerbauteil kraftschlüssig verbunden, und das Wälzlager ist auf einer der Feder, insbesondere Spiralfeder, abgewandten Seite des Trägers angeordnet. Mit der erfindungsgemäßen Maßnahme kann eine Feder-Träger-Anordnung als separates Bauteil vertrieben und als Einheit in ein Feder-Dämpfer-System integriert werden. Ohne weiteres ist schließlich mit der erfindungsgemäßen Maßnahme gewährleistet, das Wälzlager zwischen dem Karosserieteil und dem Träger unterbringen zu können. Dabei können unterschiedliche Zwischenschalenelemente eingesetzt werden, um ein individuelles Anpassen des Wälzlagers an den Träger auf einfache Weise zuzulassen. Mit der erfindungsgemäßen Anordnung des Wälzlagers auf der der Feder abgewandten Seite des Trägers ist außerdem die Montag insofern erleichtert, als die axiale und radiale Instabilität der Feder des Feder-Dämpfer-Systems, insbesondere deren hohe Zug- oder Druckkräfte, die Montage des Wälzlagers insbesondere beim Einstellen des Wälzlagerspiels nicht behindern. Überraschenderweise stellte sich mit der erfinderischen Maßnahme, jedes Federelement kraftschlüssig am Trägerbauteil anzubringen, heraus, daß die Federelement-Träger-Anordnung für spezifische Belastungen in Axial- und/oder Radialrichtung einstellbar ist. Dies ist insbesondere dann von Vorteil, wenn sämtliche Federelemente als strukturell separate Bauteile ausgeführt sind. Je nach Auslegung der Dimension und Art des Materials kann die Elastizität des Federelements eingestellt, um somit das Verhalten der Federelement-Träger-Anordnung für vorbestimmbare Belastungen wunschgemäß beeinflussen zu können.This object is solved by the features of claim 1. Thereafter, each spring element is non-positively connected to a carrier component, and the rolling bearing is arranged on one of the spring, in particular spiral spring, side facing away from the carrier. With the measure according to the invention, a spring-carrier arrangement can be sold as a separate component and integrated as a unit in a spring-damper system. Without further measures, it is finally ensured with the measure according to the invention to be able to accommodate the roller bearing between the body part and the carrier. In this case, different intermediate shell elements can be used to allow an individual adjustment of the rolling bearing to the carrier in a simple manner. With the inventive arrangement of the rolling bearing on the side facing away from the spring of the carrier also the Monday is facilitated insofar as the axial and radial instability of the spring of the spring-damper system, in particular their high tensile or compressive forces, the assembly of the bearing in particular Do not interfere with setting the rolling bearing play. Surprisingly, it turned out with the inventive measure to attach each spring element frictionally on the support member, that the spring element-carrier assembly for specific loads in the axial and / or radial direction is adjustable. This is particularly advantageous if all spring elements are designed as structurally separate components. Depending on the design of the dimension and type of material, the elasticity of the spring element can be adjusted so as to be able to influence the behavior of the spring element-carrier arrangement for predeterminable loads as desired.

Bei einer Weiterbildung der Erfindung ist das Wälzlager zwischen dem Träger und dem Karosserieteil angeordnet. Auf diese Weise ist die Montage, insbesondere das Einstellen des Lagerspiels, vereinfacht. Einflüsse durch die Spiralfeder des Feder-Dämpfer-Systems sind ausgeschlossen, insbesondere dann, wenn die Feder des Feder-Dämpfer-Systems erst nach der Montage des Wälzlagers vorgenommen wird.In a further development of the invention, the rolling bearing is arranged between the carrier and the body part. In this way, the assembly, in particular the setting of the bearing clearance, simplified. Influences by the coil spring of the spring-damper system are excluded, especially if the spring of the spring-damper system is made after the assembly of the bearing.

Bei einer Weiterbildung der Erfindung sind die Federelemente mit dem Träger fest verbunden. Vorzugsweise ist/sind mindestens ein Federelement, vorzugsweise zwei Federelemente, insbesondere das erste und zweite Federelement an dem Träger anvulkanisiert. Auf diese Weise kann ein vollkommen eigenständiges Bauteil geschaffen werden, das als einfach herstellbare Einheit bestehend aus drei Federelementen und dem Träger an der Stange des Feder-Dämpfer-Systems anbringbar ist.In a further development of the invention, the spring elements are firmly connected to the carrier. Preferably, at least one spring element, preferably two spring elements, in particular the first and second spring element on the carrier vulcanized. In this way, a completely self-contained component can be created, which can be attached as easily manufacturable unit consisting of three spring elements and the carrier on the rod of the spring-damper system.

Bei einer bevorzugten Weiterbildung der Erfindung ist die Befestigungseinrichtung modular aufgebaut. Dabei kann ein Modul durch die Anordnung aus Träger und Federelementen gebildet sein. Ein weiteres Modul ist das Wälzlager oder die Wälzlager-Anordnung bestehend aus Wälzkörpern und Laufringen. Dabei kann die Träger-Federelement-Anordnung oder die Wälzkörper-Struktur als Standard dienen, bezüglich welcher die jeweils andere Anordnung oder Struktur je nach gewünschter Betriebsanordnung abstimmbar ist.In a preferred embodiment of the invention, the fastening device is modular. In this case, a module may be formed by the arrangement of carrier and spring elements. Another module is the rolling bearing or rolling bearing assembly consisting of rolling elements and races. In this case, the carrier-spring element arrangement or the rolling element structure can serve as a standard with respect to which the respective other arrangement or structure can be tuned depending on the desired operating arrangement.

Damit ein konstantes Lagerspiel zwischen dem Wälzlager und dem Karosserieteil gewährleistet ist, ist zwischen dem Karosserieteil und dem Träger kein elastisches Federelement angeordnet. Diese Maßnahme verbessert im Gegensatz zur bekannten Befestigungseinrichtung den Montageaufwand dahingehend, daß durch elastische Elemente induzierte Freiheitesgrade bei der Montage des Wälzlagers vermieden werden.So that a constant clearance between the rolling bearing and the body part is ensured, no elastic spring element is arranged between the body part and the carrier. This measure improves in contrast to the known fastening device assembly work to the effect that induced by elastic elements degrees of freedom in the assembly of the bearing can be avoided.

Bei einer bevorzugten Ausführung der Erfindung ist der Träger im wesentlichen in einer T-Form gestaltet. Dabei kann ein Seitenschenkel dazu benutzt werden, das erste Federelement zu tragen, wobei ein anderer, dem einen Seitenschenkel gegenüberliegender Seitenschenkel dazu vorgesehen ist, das Wälzlager einerseits und das zweite Federelement andererseits zu halten. Vorzugsweise ist am Mittelschenkel das dritte Federelement derart angeordnet, daß Anschlagskräfte, die beim Durchfedern, also beim Nähern der Befestigungseinrichtung an das Dämpfergehäuse, stoßartig von dem letzteren in den Träger im wesentlichen in einer axialen Richtung eingeleitet werden, gedämpft und abgeleitet werden.In a preferred embodiment of the invention, the carrier is designed substantially in a T-shape. In this case, a side leg can be used to carry the first spring element, wherein another, the one side leg opposite side legs is provided to hold the rolling bearing on the one hand and the second spring element on the other. Preferably, the third spring element is arranged on the middle limb in such a way that stop forces, which are introduced in the axial direction during impact, that is, when the fastening device is approached to the damper housing, are damped and discharged abruptly from the latter into the carrier.

Um insbesondere Axialbelastungen möglichst schonend in den Träger einleiten zu können, ist der Mittelschenkel des T-förmigen Trägers im wesentlichen parallel zur Axialrichtung der Stange ausgerichtet.In order to be able to introduce axial loads as gently as possible into the carrier, the center leg of the T-shaped carrier is aligned substantially parallel to the axial direction of the rod.

Eine besonders bevorzugte Form des T-förmigen Trägers ist dann gebildet, wenn der Mittelschenkel verstärkt, insbesondere mit einem größeren Materialeinsatz, gegenüber den Seitenschenkeln ausgebildet ist. Dabei stellte sich heraus, daß derartig geformte Träger eine wesentlich höhere Lebenserwartung gegen Ermüdungsbruch aufweisen, als die bekannten Trägerformen. Vorzugsweise ist das Federelement aus einem Elastomer gebildet und/oder der Träger aus einem starren Kunststoff.A particularly preferred form of the T-shaped carrier is formed when the center leg reinforced, in particular with a larger material insert, is formed opposite the side legs. It turned out that such shaped carrier have a much higher life expectancy against fatigue failure, than the known Carrier forms. Preferably, the spring element is formed of an elastomer and / or the carrier of a rigid plastic.

Weiterhin betrifft die Erfindung ein Feder-Dämpfer-System mit der erfindungsgemäßen Befestigungseinrichtung.Furthermore, the invention relates to a spring-damper system with the fastening device according to the invention.

Weitere Eigenschaften, Vorteile und Merkmale der Erfindung werden durch die folgende Beschreibung einer bevorzugten Ausführung der Erfindung anhand der beiliegenden Zeichnung deutlich, die eine prinzipielle Querschnittsskizze einer erfindungsgemäßen Befestigungseinrichtung zeigt.Further features, advantages and features of the invention will become apparent from the following description of a preferred embodiment of the invention with reference to the accompanying drawings, which shows a schematic cross-sectional sketch of a fastening device according to the invention.

An einem der Stange 5 distalen Seitenschenkel 13 des Trägers 3 ist auf einer einem Karosserieteil 7 abgewandten Seite des Seitenschenkels 13 ein zweites Federelement 15 angeordnet. An dem halb ringförmig ausgebildeten zweiten Federelement 15 stützt sich eine Spiralfeder 16 des Feder-Dämpfer-Systems mit einer ihrer Endwindungen ab. Die Federkräfte der Spiralfeder 16 werden über das zweite Federelement 15 in den Träger 3 eingeleitet. Für einen gleichmäßigen Kraftfluß von der Spiralfeder über das zweite Federelement 15 in den Träger 3 ist der Übergangsbereich von dem Seitenschenkel 13 in einen Mittel- oder Längsschenkel 25 des T-förmigen Trägers 3 abgerundet. Auf einer dem Karosserieteil 7 zugewandten Seite des Seitenschenkels 13 des Trägers 3 ist eine Wälzlager-Anordnung 18 vorgesehen, die einen Montageträger 19 sowie zwei Laufringe 21 und 23 aufweist, zwischen denen eine Kugel 24 als Wälzkörper angeordnet ist. Der Laufring 23 ist an die Form der anliegenden Außenseite des Trägers 3 angepaßt.The fastening device 1 according to the figure comprises as a main component a substantially T-shaped carrier 3. At one of the rod 5 of a spring-damper system (not shown in detail) near side legs 9 of the carrier 3, a first spring element 11 is provided, which is the carrier 3 is supported on the rod 5. On one of the rod 5 distal side legs 13 of the support 3, a second spring element 15 is arranged on a side facing away from the body part 7 of the side leg 13. At the semi-annular second spring element 15, a coil spring 16 of the spring-damper system is supported with one of its Endwindungen. The spring forces of the spiral spring 16 are introduced via the second spring element 15 in the carrier 3. For a uniform flow of force from the coil spring via the second spring element 15 in the carrier 3, the transition region of the side legs 13 in a middle or longitudinal leg 25 of the T-shaped carrier 3 is rounded. On a body part 7 facing side of the side leg 13 of the support 3, a rolling bearing assembly 18 is provided which has a mounting bracket 19 and two races 21 and 23, between which a ball 24 is arranged as a rolling element. The raceway 23 is adapted to the shape of the adjacent outer side of the carrier 3.

Am Übergangsbereich 18 des Seitenschenkels 9 und Mittelschenkels 25 des T-förmigen Trägers 3 ist eine Materialschwächung durch eine insbesondere umlaufende Aussparung 20 vorgesehen, um eine zusätzliche Elastizität der Befestigungseinrichtung im Hinblick auf Belastungen in zur Axialrichtung A senkrechter Radialrichtung zu gewährleisten, welche radiale Belastung betriebsmäßig geringer als die axialen Dämpfungsbelastungen ist.At the transition region 18 of the side leg 9 and middle leg 25 of the T-shaped support 3, a material weakening is provided by a particular circumferential recess 20 to ensure additional elasticity of the fastening device with respect to loads in the axial direction A perpendicular radial direction, which radial load operationally lower than the axial damping loads.

Das erste Federelement 11 steht nicht unmittelbar mit der Stange 5 in Vulkanisationskontakt. Eine Zwei-Ring-Anordnung 22 mit einem ersten, parallel zur Axialrichtung A angeordneten Ringteil und einem dazu senkrecht liegenden Ringteil ist die Montierbarkeit der Befestigungseinrichtung 1 erleichtert, indem die Zwei-Ring-Anordnung 22 auf die Stange 5 aufgepreßt wird. Ein an der Stange vorgesehener Absatz 26 dient zur axialen Positionierung, insbesondere zum Verschrauben, der Befestigungseinrichtung 1.The first spring element 11 is not directly in contact with the rod 5 in Vulkanisationskontakt. A two-ring arrangement 22 with a first ring part arranged parallel to the axial direction A and a ring part lying perpendicular thereto facilitates the assemblability of the fastening device 1 by pressing the two-ring arrangement 22 onto the rod 5. A provided on the rod paragraph 26 is used for axial positioning, in particular for screwing, the fastening device. 1

Das erste Federelement 11 zur elastischen Kopplung der Befestigungseinrichtung an die Stange 5 ist derart dimensioniert, insbesondere mit einer derartigen Dicke versehen, daß eine Kippbewegung der Befestigungseinrichtung 1 um die Axialrichtungsachse (A) möglich ist. Auf diese Weise wird dem Feder-Dämpfer-System auch eine Flexibilität in Radialrichtung verliehen. Die Kippbewegung wird auch durch die Aussparung 20 des Trägers 3 hervorgerufen oder verstärkt.The first spring element 11 for the elastic coupling of the fastening device to the rod 5 is dimensioned such, in particular provided with such a thickness that a tilting movement of the fastening device 1 about the axial direction axis (A) is possible. In this way, the spring-damper system is also given a flexibility in the radial direction. The tilting movement is also caused or reinforced by the recess 20 of the carrier 3.

Um ein stabiles Abstützen der Spiralfeder 16 an dem Träger 3 gewährleisten zu können, erstreckt sich der Seitenschenkel 13 des T-förmigen Trägers über den Belastungseingreifmittelpunkt M der Endwindung der Spiralfeder 16 radial hinaus.In order to ensure a stable support of the coil spring 16 on the support 3, the side legs 13 of the T-shaped support extends radially beyond the load engagement center M of the end turn of the spiral spring 16.

Am freien Ende des Mittelschenkels 25 des T-förmigen Trägers 3 ist ein den Mittelschenkel 25 im wesentlichen axial verlängerndes drittes Federelement 27 entweder direkt oder über eine Verbindungshülse 29 befestigt. Der Mittelschenkel 25 des T-förmigen Trägers 3 ist im wesentlichen parallel zur Axialrichtung A der Stange 5 ausgerichtet. Das dritte Federelement 27 dient als elastischer Anschlag am Dämpfergehäuse 28 für zu große Einfederwege des Feder-Dämpfer-Systems.At the free end of the central limb 25 of the T-shaped support 3, a middle spring 25 is substantially axially extending third spring element 27 is attached either directly or via a connecting sleeve 29. The center leg 25 of the T-shaped carrier 3 is aligned substantially parallel to the axial direction A of the rod 5. The third spring element 27 serves as an elastic stop on the damper housing 28 for too large compression travel of the spring-damper system.

Wie aus der Figur ersichtlich ist, umfaßt die erfindungsgemäße Befestigungseinrichtung im wesentlichen zwei Moduleinheiten bestehend aus einerseits einer Federelement (11, 15, 27) - Träger (3) - Anordnung, die als Fertigungseinheit an der Stange 5 befestigbar ist. Andererseits wird eine Einheit durch die Wälzlager-Anordnung 18 gebildet, die zum Verbinden der Federelement-Träger-Einheit an das Karosserieteil 7 eines Kraftfahrzeugs (nicht dargestellt) befestigbar ist.As can be seen from the figure, the fastening device according to the invention essentially comprises two modular units comprising, on the one hand, a spring element (11, 15, 27) - carrier (3) arrangement, which can be fastened to the rod 5 as a production unit. On the other hand, a unit is formed by the rolling bearing assembly 18, which is fastened for connecting the spring element-carrier unit to the body part 7 of a motor vehicle (not shown).
